A group of individuals who made vague threats about assassinating presumptive Democratic presidential nominee Barack Obama posed no threat to the Illinois Senator, US officials say.

The three men in question were high at the time of their arrest on gun and drug charges but would have been unable to carry out any attack, Colorado federal prosecutor Troy Eid says. Any attempts to kill Obama equaled little more than the “racist ramblings of three meth heads.”

During the arrest of the three men, one suspect attempted to escape by jumping from the sixth floor of a Denver hotel, breaking his ankle in the process.

Threats to Obama were uncovered during a police interview with the suspects. "He don't belong in political office or blacks don't belong in political office,” Nathan Johnson said.

Johnson denied being involved in any assassination plot, but implicated the other two men, telling police they wanted to shoot Obama “from a high vantage point.”

Obama will officially accept the Democratic nomination tomorrow at Invesco Field. The stadium holds 75,000 people.

His acceptance speech will also be 45 years to the day that Dr. Martin Luther King Jr. made the famous “I Have a Dream” speech.
